One of the ways computers distinguish humans from robots is with CAPTCHAs — that little box with a weird letter combination at the bottom of your online ticket or other transaction. Researchers report they've now trained a computer to solve CAPTCHAs using less data than other AIs by borrowing the human brain's approach to the problem.
The big picture: This isn't about cracking CAPTCHAs, but a much larger effort to create AIs that use principles of the human brain to solve visual tasks — like recognizing a cat from a dog with not a lot of examples to go on. AI pioneer Geoffrey Hinton recently told Axios he suspects the current approach of giving computers lots of rules and labeled data is limited, and that researchers should look again to the brain to make material advances in AI. This is a step in that direction.
